Comments "...conduction distances within the CNS can be quite long, especially in larger brains and within the spinal cord, and axonal delays can vary greatly. For example, some corticospinal neurons of monkeys generate impulses that require as little as 0.6 ms to reach the brain stem ~ 70 mm away, representing conduction velocities of up to 110 m/s. Such values are as high as any seen [in] the peripheral nervous system."
